Abstract
The geothermal system within the Alvord basin, Harney County, Oregon discharges bicarbonate-rich water at three hot-spring areas. System recharge by meteoric water occurs the Steens Mountain-Pueblo Mountain fault block. Water circulates to at least 2.5 km before rising along range-front and faults. Minimum reservoir temperature estimated near 200' C and residence time the system may be over 10,000 years. Flow pathways, volume, and boiling account for compositional differences in spring discharges.
